I like. The reverse guitar/synth sounds you have in the beginning are very nice, they add up for a very nice ambient track. Maybe instead of breaking in the full time drums, double time them. Make them slow, and break into that little groove you have later with the square lead. It would add a bit more groove, me thinks. Some wind FX wouldn't hurt (high resonance 3X0sc with lots of delay and reverb with a rising filter cut) just so it could add a litle bit more of a 'build' feel when a build is comin' up.
I like the drum work you put into this one a lot. Good work, I am impressed. Keep it up!
Could you drop by my audio page and drop a review or two? I'd appreciate it =D
